Complex and expensive instrumentation is currently required to test the NOAA Weather Radio (NWR) receivers because of their unique characteristics. There is a critical need for a small, portable, dedicated broadcast simulator specifically designed to evaluate NWR system performance. This SBIR Phase I project covers the research directed toward designing, prototyping, and establishing the feasibility of such an all-in-one testing tool, a NWR Broadcast Simulator. This simulator automatically performs comprehensive measurements for testing the performance of the NOAA Weather Radio (NWR) receivers and assessing compliance with the Public Alert Standard CEA-2009. In Phase I a prototype of a NWR Broadcast Simulator will be built and tested to establish proof-of principle. In Phase II a fully engineered simulator will be built, characterized and delivered to NOAA and potential commercialization partners. POTENTIAL COMMERCIAL APPLICATIONS The NWR Broadcast Simulator will be market and sold in collaboration with one or more strategic partners to any company selling weather radios and other emergency radio equipment, for example Radio Shack or Target. Another market segment is the Weather Radio manufacturers who will use it as a test system
